WHEEL FOR SAWMILL-CARRIAGE TRUCKS.

Be it known that l, (iiis'rAv E. STLHKKE, :i suhjeet of the King of Norway. residing at Rose Lake. in the county oi Kootena'i nnd State of hlnho. have inveiited, certain new and useful Impwwements in Wheels for Snwinill-Cnrriuge 'lrueiis, of which the following: is n spi'acifiontion.

My invention relates to an in'iprovement in wheels for suw-niiil C:1[['i2lg-tlHClS. it is ries lied to overemne the objection. due to excessive wear of one oi the two wheels. namely the tint wheel, which usually Wen-rs down :t the rim of anywhere from threeeighths to iw-cighths of an inch per year as compared with the wear of the V-wheel, which is n the neighborhood of one-sixteenth of an inch per year.

The object of my present invention, therefore. to g rovide extra replaceable tires for the lint wheel. such as could he carried on hand and. easily substituted for-a Worn tire thus greatly lengthening the life of the wheel and {it the same time avoiding the mi-hing down of the V-wheel periodically to corrcspoml ith the size of the flat Wheel. thus in short greatly prolonging the life of both the lint ou V-wheels.

in tilt' :iccoinlmnving drawings: Figure l is :1 view in perspeetin: of an axle showin two 'rrn 'lcwl.-w. ls. one the so-cnllcd flat wheel. and the other the V-wheel: and Fig. 2 is an enlarged sectional View through my improved wheel. inning n. removable and replaceable tire.

The numeral 1 represents the wheel-huh, and 2 is the removable. tiie or rim. The periphery S of the Wheel-(enter l is tapered,

and the here 4 of the tire tapers correspondingly. The length of the. wheel-center is greater than the thickness of the tire, and one end 5 is larger than the corresponding end of the here of the tire, so that the wheel-center ivill not pull through the tire. The opposite end of the wheel-center has screw-threads G. A lock-nut 7 screws upon these threads, and is provided with notches S at the outer edge to receive a. spinner by which it is screwed tightly in piaee, thus making a solid wheel when screwed in place, Q

consisting of the hub wheei-eenter, tire and lock nut. In this way, it is repeated. the main portion of the wheel may be used over and over again since practically ali. the wear is upon the tire, which tire is by this invention renewable and replaceable. When. the lock-nut is screwed up tight, the wheel-center and tire are forced together on the taper from the tapering cont-acting surfaces. so that they are made perfectly tight, and as if in a single piece.
